が使用される。The present invention relates to a method for extremely easily manufacturing a catalyst electrode for a fuel cell with excellent characteristics. A carbon molded body containing a catalyst such as platinum or palladium is generally used as a fuel electrode for various fuel cells that use hydrazine, methanol, or the like as a fuel.

が煩雑であるばかりでなく、ポリアト゛ラフロロエチレ

電極の電気抵抗が大きくなつてしまう、という欠点があ
つた。(Support) Only the carbon particles are first bound onto the electrode substrate by the method shown in (1), and then the catalyst is supported. At this time, as a method used for supporting the catalyst, an electrolytic reduction (electrodeposition) method, a gas phase reduction method using hydrogen gas, a liquid phase reduction method using formalin, etc. are used. However, these conventional catalyst electrode manufacturing methods not only involve complicated manufacturing processes, but also use plastics such as poly(atrafluoroethylene) as a binder.
The drawback was that the electrical resistance of the electrodes increased.

点を除去し、操作が極めて容易で、かつ、電導性の高い
触媒電極を容易に形成することができるような触媒電極

の結着剤なしに、電極基体上に均一かつ強固に固着させ
るものである。In order to achieve the above object, the present invention immerses an electrode base in a catalyst solution in which carbon powder is suspended, and performs electrodeposition using this as a cathode. In addition, it can be fixed uniformly and firmly onto the electrode substrate.
以下、実施例を用いて本発明を詳細に説明する。実施例
１第１図は、本発明によつて触媒電極を製造するため
に用いられる装置の一例を示す模式図である。Hereinafter, the present invention will be explained in detail using Examples. Example 1 FIG. 1 is a schematic diagram showing an example of an apparatus used for manufacturing a catalyst electrode according to the present invention.

なつた。0.01 mol/l of chloroplatinic acid (H2ptC26) and 0.005 mol/l of rhenium heptoxide (Re2O,)
Activated carbon powder having a particle size of approximately 5 μm was suspended in the solution at a ratio of 25 t/2 to form an electrolytic solution.
1.61 of this electrolytic solution 3 is put into a container 4, and while circulating the electrolytic solution 3 using a pump 5, a tantalum extract band metal mesh 1 (area 120 cr!
Electrodeposition was performed by using i) as a cathode and applying a voltage between both electrodes.
電流密度２０ｍＡ／Ｃｔｉｉで１．５時間電解を行なう
と、電解液中に含まれる白金はすべて陰極１上に析出し
、陰極１上の白金析出量は、ほぼ３０７Ｖ／Ｃｔｌｔで
あつた。When electrolysis was carried out for 1.5 hours at a current density of 20 mA/Ctii, all of the platinum contained in the electrolytic solution was deposited on the cathode 1, and the amount of platinum deposited on the cathode 1 was approximately 307 V/Ctlt.
また、陰極１には白金とともに炭素も析出し、その析出

手でこすつても剥離せず、燃料電池の触媒電極として、
実用上十分な強度で固着されていることがわかつた。In addition, carbon is deposited on the cathode 1 along with platinum, and the amount of the deposit is approximately 10T! It was 1f1/Cd. The thickness of the deposited layer was approximately 0.5 mm. These platinum and carbon do not peel off even when strongly shaken with a tantalum mesh or rubbed by hand, and are used as catalyst electrodes in fuel cells.
It was found that the bonding strength was sufficient for practical use.
周知のように、炭素粉自体が電解液中でイオン化するこ
とはないから、炭素粉は電解あるいは電着によつては析
出しないものと、一般には見做されて卦り、炭素粉のみ
を含む懸濁液を電解しても、炭素粉は析出しない。As is well known, since carbon powder itself is not ionized in the electrolyte, it is generally assumed that carbon powder is not deposited by electrolysis or electrodeposition, and contains only carbon powder. Carbon powder does not precipitate even if the suspension is electrolyzed.
本発明は、炭素粉のみを含む懸濁液ではなく、触媒を溶
解した液に炭素粉を懸濁させた液を電解して、炭素粉と
触媒の両者を陰極上に析出固着させるものである。The present invention does not use a suspension containing only carbon powder, but electrolyzes a solution in which carbon powder is suspended in a solution containing a catalyst to deposit and fix both the carbon powder and the catalyst on the cathode. .

金が析出し以下、これがくり返されることによつて炭素
粉が白金の針状結晶で架橋された形で触媒層が形成され
るものと推定される。The reason why carbon powder precipitates when the catalytic force ζ coexists is not necessarily clear, but platinum first precipitates on the cathode as thin needle-like crystals, becomes entangled with these needle-like crystals, and then forms carbon powder. It is presumed that the carbon powder is fixed, further acicular platinum is precipitated on top of the carbon powder, and as this is repeated, a catalyst layer is formed in which the carbon powder is cross-linked with platinum acicular crystals. be done.

線ｂ卦よびｃに示した。Therefore, even if a voltage is applied to a suspension of carbon powder that does not contain a catalyst, precipitation of carbon powder will not occur, so not only carbon powder but also a catalyst must coexist in the liquid. It is necessary to be present. When the catalyst electrode thus obtained is used as a methanol electrode in a methanol fuel cell,
The potential-current density characteristics of the electrode are shown in curve a in Figure 2.
As the electrolyte, sulfuric acid is 3 mol/l and methanol is 1 mol/l.
A solution containing mol/l was used. For comparison, the characteristics of the catalyst electrode formed by the conventional method are shown in curves b and c of FIG.

The following are the results obtained by using a polytetrafluoroethylene emulsion.

上昇してしまうことはない。Well, the amount of platinum supported in each of the above electrodes is 3077V/
The electrode substrate for each CF7l was the tantalum expanded metal net (used in this example).
The same surface area (120 cd) was used. As is clear from curve a in Figure 2, in the case of the electrode formed according to the present invention, the relationship between the logarithm of current density and potential is almost linear, and even if the current density increases, the potential changes accordingly. It will not rise to an extreme level.
しかし、曲線ｂ卦よびｃに示したように、従来の方法に
よつて形成された触媒電極は結着剤（テフロン）を用い
ているため、電極抵抗が増大する結果電流密度と電位の
間の関係が直線にならず、電流密度を大きくすると電位
が蓄るしく高くなつてしまう。However, as shown in curves b and c, the catalytic electrode formed by the conventional method uses a binder (Teflon), which increases the electrode resistance, resulting in an increase in the current density and potential. The relationship is not linear, and when the current density is increased, the potential accumulates and becomes higher.
いうまでもなく、燃料電池の電圧は、対電極（空気極）
と触媒電極の電位差で表わされるから、触媒電極の電位
が上昇することは、燃料電池の電圧がそれだけ低下する
ことを意味し、所定の電圧を得るためには、多数の電池
が必要となる。Needless to say, the voltage of a fuel cell is determined by the voltage at the counter electrode (air electrode).
Since this is expressed as the potential difference between the catalyst electrodes, an increase in the potential of the catalyst electrodes means that the voltage of the fuel cell decreases accordingly, and a large number of cells are required to obtain a predetermined voltage.
特性が極度に不良である曲線ｃは別として、曲線ｂの場
合と本発明を比較してみる。燃料電池として実用に供し
得るためには少なくとも５０〜１００ｍＡ／Ｃｄの放電
電流密度が必要である。Let us compare the present invention with the case of curve b, except for curve c, which has extremely poor characteristics. In order to be put to practical use as a fuel cell, a discharge current density of at least 50 to 100 mA/Cd is required.
゛ここで、１００ｍＡ／Ｃｄの電流密度で放電したとき
の電池の電圧を第２図を用いて計算すると、本発明によ
つて形成された触媒電極の電位は０．４８になるのに対
し曲線ｂの場合の電位は、第２図から明らかなように、
ほぼ０．６である。空気極の電位はほぼ０．９Ｖである
から、両者を用いたときの起電力はそれぞれ卦よび
となる。゛Here, when the voltage of the battery when discharged at a current density of 100 mA/Cd is calculated using Fig. 2, the potential of the catalyst electrode formed according to the present invention is 0.48, whereas the curve As is clear from Figure 2, the potential in case b is
It is approximately 0.6. Since the potential of the air electrode is approximately 0.9V, the electromotive force when both are used is a trigram.
したがつて、起電力１００Ｖを得るために必要な電池の
数は、本発明の場合は、１００÷０．４２−２４０個
曲線ｂの場合は、
１００÷０．３−３３０個
となり、本発明によれば、従来よりも所要電池数を著る
しく低減できることがわかる。Therefore, in the case of the present invention, the number of batteries required to obtain an electromotive force of 100 V is 100 ÷ 0.42-240.In the case of curve b, the number of batteries required is 100 ÷ 0.3-330. According to the above, it can be seen that the number of required batteries can be significantly reduced compared to the conventional method.
さらに、本発明は、電極基体を単に懸濁液中に浸漬して
、液を攪拌しながら電着するのみでよいから、従来のよ
うに触媒の担持と炭素粉の塗布の２工程を要する方法に
くらべて、はるかに簡便で容易である。Furthermore, the present invention requires only immersing the electrode substrate in the suspension and electrodepositing it while stirring the liquid, so unlike the conventional method, which requires two steps of supporting the catalyst and applying carbon powder. It is much simpler and easier than

して懸濁させ、電解液を形成した。In addition to the carbon powder and the catalyst, at least one of rhenium, osmium, tin, ruthenium, etc. can also be fixed as a co-catalyst. Example 2 In a solution in which nickel sulfate and chloroplatinic acid were dissolved at a ratio of 0.01 mole/square and 0.003 mole/2, respectively,
Activated carbon having a particle size of approximately 5 μm was added and suspended at a ratio of 2.5 f/2 to form an electrolyte.

適である。As a result, all of the nickel and platinum in the electrolyte are deposited on the electrode, and the amount of carbon powder deposited is approximately 15 cm/cm.
It was Crii. Similarly to the case of Example 1, the nickel, platinum, or carbon powder of the catalyst electrode thus formed did not come off even when rubbed by hand or strongly shaken. The catalyst electrodes formed in Example 1 and Example 2 are extremely suitable as catalyst electrodes for methanol-fuel cells and hydrazine fuel cells, respectively.

It can also be used for gas electrodes. In the present invention, an acidic solution containing sulfuric acid, phosphoric acid, etc. is normally used as the electrolytic solution, but an alkaline solution containing sodium hydroxide etc. may also be used.
